My fiance and I are planning our honeymoon from the United States to Portugal and will be flying in and out of Lisbon. We've decided to do 5 days and Lisbon and 4 days in Porto, with a few buffer days for travel. We are debating between heading for the train to Porto immediately after landing in Lisbon, or starting in Lisbon then going to Porto, and then returning for one night in Lisbon before catching our plane home.
My question is: how much of a hassle is it to get to Porto from the Lisbon airport? Do you think it's better for us to go there first so we don't have to spend one day at the end of our trip getting back to Lisbon? Or do you think it's better to stop once we get to Lisbon even if that means we have to return for our last night?
Thanks in advance for your help!
